Fun conversation with @jkxosound.com about where I think things are going in the AI agents space, Strands Agents, and rats 🐀
@clare.dev is one of the leaders making AI engineering simple and scalable at AWS. Had a great time chatting with her as we discussed Strands Agents and patterns like “Retrieval as a Tool”.

Really appreciate the depth at which the Hex team broke down their Text-to-SQL implementation. Everyone's trying to teach LLMs SQL like it's a training problem but it's really a graph traversal problem.

In my post about #DuckDB I digress into the role of the database buffer cache to discuss how we segregate transactional workloads from analytical. DuckDB turned out to be a natural, lightweight approach to offloading analytical queries ensuring our application upheld performance requirements.

Instead of materialized views, we built in-process DuckDB caching in the control plane of Striim Developer — improving query performance 5–10x with zero added infra.

This was actually my longest podcast ever at over 70 minutes. Not sure I could have made it any shorter because nerding out on databases with Andy Pavlo was too fun.
Was super fun chatting with @andypavlo.bsky.social
to kick off the new season of What's New in Data. We dive into vector databases, text to sql, trends in data infrastructure, and Andy's awesome (and open) database course.

Just found out one of the internal b2b CRUD app vendors is more like CRD because it doesn't support updating submissions. AI gonna cook that sector so hard.

Unfortunately the bar of complexity for streaming has been set so high. I'm calling it Streamholm Syndrome.

I'm not sure whether to be more amazed at the hate for FiveTran's price increase or the fact that Reddit doesn't know Striim exists and are proposing batch solutions to this persons obvious streaming CDC use case.

A single Striim cluster (multi-node for scalability and fault tolernace) can handle 35k, very wide, very active databases that produce millions of DML per hour hour and dozens of DDL per day. The 'intelligence' layer or Striim was able to apply rule based logic on how to handle complex DDL.

I will die on this hill but MySQL's 'Alter Table Add Column AFTER' DDL is pointless. It doesn't change the layout on disk. If you care about order of the columns, that's purely a read side construct and you should address it in your query not your DDL!

I always love seeing clovers in the wild! Knowing every transaction is streamed to Snowflake in real time with Striim’s streaming CDC service. We do a lot of work to ensure transactions are bound reliably and replicated with no duplicates while maintaining low latency.

When I saw the fire up the hill, I knew we wouldn't have much time to get out before the only escape road would become gridlocked. I texted my friends up on Lachman Ln an hour before they got an alert from the city to leave.
